As soon as I saw the title I suspected the exploit was probably markdown related, as I had fixed pretty much the exact same issues in VS Code. Two things to keep in mind when developing electron apps: - The potential impact of an XSS or other security exploits is much higher. You can limit the impact of most of these with additional layers of security, such as running untrusted html in isolated environments with node integration disabled. However, also remember that... - Many security features are opt-in. Content security policies (CSP) are a good example. Pages without a CPS default to allowing anything, which sort of makes sense in browser world for backwards compatibility, but is not a good idea for desktop apps.
